Step 1

Preheat oven to 375F.

Step 2

Combine olive oil, melted butter or non-dairy spread, garlic, spices, salt and pepper and half the cilantro in a small mixing bowl; stir to combine.

Step 3

Spread 1-2 tablespoons of the mixture in the bottom of a 9 x 13 inch baking dish.

Step 4

Arrange sweet potato slices in the dish and brush potatoes with the remaining olive oil mixture, reserving a couple of teaspoonfuls.

Step 5

Cover with foil and bake for 45 minutes.

Step 6

Remove foil and increase oven temperature to 450F.

Step 7

Roast potatoes for an additional 15 minutes, or until potatoes are slightly browned. Allow an extra 5 to 10 minutes at high altitude or if your sweet potatoes are large.

Step 8

Remove sweet potatoes from the oven and test an end piece for doneness. If the sweet potatoes have dried out during roasting, brush them with reserved seasoned olive oil.

Step 9

Garnish with cilantro leaves.
